| Abstract: |
| Implementation of digital channelization is presented based on polyphase filters
and s
tructure of the uniform filters and 50% overlap of subchannels division. The
contradiction between high-speed real-time processing and FPGA processing s
peed is solved, and the blind spot of the channelized receiver is overcome. The
idea
and method for implementing HF broadband digital channelization based on
FPGA is proposed. Simulation shows the design has strong practicality and vers
atility. |
